Description
Technical field：
The present invention relates to a kind of RMB anti-counterfeiting printing technology, particularly a kind of single parameter variable transmutation ternary layered encryption two enters
RMB anti-counterfeiting printing process processed, this RMB anti-counterfeiting printing technology can be used for the anti-counterfeit printing of the RMB of various face amounts
In.
Background technology：
Currency security is related to a national financial security, starts struggle that is false proof and faking from currency generation and does not just stop
Breath, the RMB of China is audaciously innovated, and employs watermark anti-counterfeiting technology, safety line anti-counterfeiting technology, carved intaglio print
Brush and gravure wiring anti-counterfeiting technology, red blue color fiber and colorless fluorescent fiber anti-counterfeiting technology, stealthy denomination digital anti-counterfeiting technology,
